BINDING-BAR.

SPECIFICATION forming part of Letters Patent No. 404,865, dated June 11, 1889.

Application led October 20, 1888.

T all whom, t may concern; Y

Be it known that I, J oHN T. RICHARDSON, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Binding-Bars for Spring Railway-Frogs; and I do hereby declare that the following is a full, clear, and exact statement and description of the invention, which will enable others skilled in the art to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this speciiication. My invention relates to railway-frogs; and it consists, specifically, in the construction of binding bar s or clamps forrailway sprin g-fro gs by which I secure a most efficient mode of binding the tongue of the frog to the rigid rail thereof, (the ordinary filling and side supporting-blocks being used for spacing purposes,) said binding-bars passing under the rails and being held thereto securely, as hereinafter more fully set forth.

In the drawings, Figure l is a plan view of a spring-frog provided with my improvement. Fig. 2 is a transverse section on the line X X of the binding-bar nearest to the heel of the frog with the guide in place. Fig. 3 is a 3o vertical section on the line Y Y of the binding-bar supporting the apex of the tongue. Fig. 4L shows the locking-lug detached. Fig. 5 is a perspective view of one of the bearing and binding bars or plates.

In the drawings, A designates the fixed or rigid Wing-rail of the frog, B the movable Wing-rail, and C the tongue of the frog formed by the converging rails D.

The spring inclosed in the housing E is of ordinary construction, and operates when at rest to hold the movable rail in lateral contact with the tongue of the frog while it admits of contraction under the conditions of shunting. The bearing and binding bars or plates F and F pass beneath the frog and wing-rails, the former near the heel and the latter near the point of the frog. The ends b and b of these bars adjacent to the fixed rail are turned upward, so as to support the side spacing-blocks a a, and are perforated Serial No. 288,637. (No model.)

for the purpose set forth in full in Letters Patent granted to me October 20, 1885, No. 328,810, in the manner therein described. The opposite end of the binding-bar F is turned upward to constitute a stop c to limit the outer 5 5 lateral movement of the movable wing-rail B when the latter is forced away from the contact with the tongue O by means of the Wheelflanges of a shunted train. Said bindingbars are perforated at CZ d at or about their 6o longitudinal centers for the reception of the smaller ends e of theV locking-lugs f. The binding-bar F', differs at its end neXt to the movable Wing-rail from the corresponding end of the bar F, as shown in Fig. 5, on account of its function in supplying a bearingsurface to which the guide g of the movable rail is bolted.

The lugs f, as shown in Fig. 4, are recessed or shouldered on theirvertical lateral edges 7o to form an expanded head, a reduced stem part e, and an intermediate portion, it having two'shoulders s s on each edge, the shoulder s to rest when the lugs are in position on the horizontal upper surface of the binding-bars, 7 5 and the shoulder s on the flange of the tongue C. The projecting stem ends c of the lugs f are shaped to fit accurately into the elongated holes d CZ, and are riveted or otherwise sccurely fastened therein, but preferably by 8o means of the keys 7c.

The clamps or binding-bars being put into place-and the lugs f made to iit into their respective seats e' in the iiange of the tonguerail C, are forced tightly thereinto by the binding key-blocks a a on the outer side of the rigid wing-rail, all the stationary parts of the frog being bound securely together. The shoulders s of the lugs f prevent the binding-bars F F from dropping downward from 9o any cause whatever. The lug f in the binding-bar F is perforated from its outer vertical surface to receive ythe smaller inner end of the guide g, the opposite end l thereof being bolted to the underlying free end of the bind- 'ing-bar F.

lateral. movement of the same, retaining it in the proper plane of movement at all times, and thus overcoming; all tendency to tilting` or rising,1 thereof. The downward curve of the guide g performs the important function of a stop to limit, in connection with the outer l'langed end c of the binding-bar F', the outer lateral motion of the movable wing-rail B. Upon examina-tion it is seen .that an additional advantage is gained by the horizontal extension of the binding-bars from the fact thatl frietional bearing-surfaces for the support of the movable wing-rail A are thereby secured, and all the parts of the frogI are .retained in the same plane.-

Having` thus described my invention, what I claim7 and desire to seenre by Letters Patent, 1s'- 1. ln a railway-frog, the combination, with the tongue-rails, one of which has a notched llang'e, of the bearing;` -plate npon which the said rails rest, and the locking-lug having an expanded head resting1 upon the said rail flange and also resting in the notch therein and seenred to the said ll'vlate, substantially as set forth.

2. In a railway spring-f1'og,tl1e combination of the tollg'ue-rails, the fixed wing-rail secured to the tongue-rails, the movable wing-rail, the bearing-plate beneath the said rails, and a lng` secured to the said plate situated between the movable wing rail and the adjacent tongue-rail, and having' an expanded head engaging with the flange et the tongue-rail, substantially as set forth.

3. The combination, with the tongne-ralls and the wing-rails, of the bearing-plates below the said rails, and the loeking-lngsf, having" shouldered edges, seated in notches in the flange ot' the tongue-rail and passingthrongh the said plates, to which they are secured hy keys, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presen ce ol two subscribing' witnesses.
